We sail with P&O, Celebrity , NCL and RC. Next is Anthem. That will move us up to Diamond. Once there, the perks are better than P&O and Celebrity, but NCL is good as well. We mix Southampton departures with fly cruises. P&O are generally at the top of our list, but only just. We don't intend to Cruise with Saga, or Cunard, but may give Princess a go....Very loyal We are🤣
